This invention relates to railroad refrigerator cars used to transport perishable commodities at a predetermined temperature. The invention is applicable particularly to cars wherein the cooling means, preferably containers for solid refrigerant, are disposed immediately below the roof of the car. The lading is supported in spaced relation to the door by a foraminous rack. Flues, preferably associated with the side walls of the car, communicate between the cooling means and the space under the floor rack to provide a path for the circulation of air. Said path is from the cooling means downwardly through said fiues through the space under the floor rack, upwardly through the lading compartment, thereby cooling the lading, and finally to the cooling means from whence the cycle is repeated.

The containers may be of any of several types, either foraminous when water ice is used, partly forarninous and partly imperforate when ice and salt is used, or wholiy imperforate with drain and overow openings.

Drip pans are provided immediately below said containers to catch the liquid therefrom and conduct the same to and into said nues. The liquid dripping from saidvcontainers onto said drip pans is subject to a certain amount of surging thereon due to service movements oi the car, and consequently provision must be made to prevent such surging liquid from leaving said drip pan and falling within the lading compartment, which is one of the objects of the invention. li certain types of these refrigerator cars, the doors thereof are provided with flues which, when the doors are closed, register with the wall fiues above and below the doors and conduct moisture and air therethrough to the bottom of the car. Thus when the doors are open, as when the car is being loaded, the drippage falls from the top of the doorway to the great annoyance of the persons loading the car, An object of the invention is to provide a fiashing at the upper edge of the car lining and top of the flues extending over the doorways of the car to prevent the possibility oi such drippage in the doorway.

It is another object of the invention to provide such flashing, either wholly upon the side wall of the car at the top of said flue, or wholly upon the adjacent edge of said drip pan, or upon cooperative parts of said flashing on both the wall and drip pan.

A further object of the invention is to provide such iiashing, either for the drip pan or the car above the lining, constructed and arranged to prevent moisture from the drip pan contacting the car posts or dripping into said doorway.

A still further object of the invention is to provide such flashing with bafiles to prevent moisture thereon from draining over the edges thereof and then moving longitudinally of said edges by capillary attraction into contact with said posts, or into said doorway or into said lading compartment,

Other objects and advantages of the invention will appear in the following detailed description thereof.

Referring now to the accompanying drawings forming part of this application and wherein like reference characters indicate like parts.

Figure 6 is a top plan view of Figure 4 showing in section the associated side wall flue, door posts and inner posts.

Figure '7 is a broken perspective view of the portion of the flashing shown in Figures vi, 4, 5 and 6 extending over the doorway.`

In the drawings the general parts of the refrigerator car shown are insulated roof 2; side wall 3; floor li; hatch 5; refrigerant container t; side wall fines 1; foraminous floor rack 8; and space 9 between the rack 8 and iioor fi. The refrigerant container S is positioned directly below the roo-f 2 and adjacent a side wall 3. A drip pan l2 is provided below the container, and a partition lll is disposed in an upstanding position atl the inner edge of the drip pan i2. The drip pan i2 and partition lll cooperate with the roof and upper part of the side wall forming a cooling compartment about container t, said cooling compartment having an inlet i5 between the upper edge of partition ld and the car roof, and an outlet il between the o uter edge of drip pan I2 and car wall adjacent flue i. rihe warm air from the lading compartment rises and enters cooling com partrnent through inlet i5, is cooled therein and falls by gravity through discharge opening Il and flue l, to space 9, whence it rises through rack t to the lading compartment i3.

The side wall comprises a series of spaced outer posts 25 and a series of spaced inner posts 26. Fluo sheets 28 extend between and are secured to inner surfaces of inner posts 26 and are provided with outwardly projecting panels 29 between said posts 26. Door posts 30 are shown at either side of the doorway 30 therebetween. A lining 3l is disposed natwise against and secured to posts 26 and door post 3U, thereby forming side wall flues 'l between the lining and outwardly projecting panels 2S of the flue sheets 28, and the outer edge of the drip pan I 2 occurs in substantially the same vertical plane as the lining-3l but spaced slightly thereabove.

In the modication shown in Figures 1, 4, 5,v 6. and 7, there is provided a dashing extending from end to end of the car and adapted to be secured to the inner posts 26, said dashing comprising a downwardly extending vertical body portion 32V which is adapted to be secured to said posts 26 between said posts and upper part of lining 3l, which part of said lining is rabbeted to receive same. Said dashing alsovcomprises a substantially horizontal portion 33 which extends inwardly and slightly upwardly over the upper edge of said lining 3| and is then bent upwardly at a greater angle formi-ng a marginal flange 31%, all as clearly shown in Figure 7. Thel portions 33 and 34 are continuous from end to end of the car and form a gutter at the side of the car under the outer edge of the drip pan, but the portion 32, at points on opposite vertical edges of the doorway and each post 26 is slit and the material between said slits is bent to extend upwardly, as shown at 32. A vertically disposed angle piece is shown, having one flange 3S thereof secured atwise to the vertically extending adjacent edges of portions 32 and 32 so that the other flange 3i extends normal thereto and acts as a baille to prevent water dripping into said doorway or against said posts-as hereinafter described.

Were it not for these baiiies 35 water in said gutter running over the downwardly extending portions 32 might, because of surging due to service movements of the car, or capillary attraction, move longitudinally along said portion 32 or elsewhere until in contact with a post, or over the lading. space and drip thereinto, either of which, of course, is very undesirable. Also any moisture from the drip pan ilowing into portions 33 and 3dwill be effectively prevented by the portions 3,2 from contacting posts 26 or dripping into said doorway. As shown in Figure l, drip pan l2 may have a counterflashing extending from the outer lowerA edge thereof into saidgutter-like portion Sil-315 to direct liquid from the drip pan thereinto. In the modification shown in Figures 2 and 3 the drip pan i2 is provided along its outer edgelwith a flashing 40, which underlaps the outer margin of said drip pan, and the outer margin of' said flashing dis bent downwardly, as at 4|, inv overlappingV relationship with lining 3l. The containers G are longitudinally spaced along the upper outer portion of the car, and each container is provided with a drip pan I2 thereunder. The ends of the flashing 40, beyond the sides of the drip pan l2, are turned upwardly thereagainst forming the flanges 42, and the portion 4| is slit at a point inwardly from its ends and the end portions beyond said slits are turnedupwardly, as at 46. A vertical baille 45- is secured along one edge to the adjacent edges of portions 44 and 4I, said baille `llextending normal thereto, as shown in Figure` 3. Thus any moisture within or dripping upon the corner post of drip pan l2 will be prevented by the flanges 42 and 44 from draining frpxn the. drip pan outwardly of the baille 45.

In Figure 3 baille 45 is shown as formed from flat plate secured along one edge to the edges of portions 4I and 4B and functions precisely as the iiange 35 of angle 3S.

A similar arrangement is provided for that portion of the drip pan which extends over the doorway. On a line adjacent each side of said doorway, portion 4I is slit and the material between the slits bent upwardly, as at $6. Likewise a similar arrangement is provided when the lower edge of the drip pan passes a post. Of course, bailies 45- are .provided similar to baiiles i5 and for the same purpose. Consequently the drip pan flashing is, provided with the downturned portions 4l to direct moisture from said pan over the top of lining 3l and into ues l between the posts, and with upturned portions t4 and t3 to prevent moisture from said drip pan from contacting any post, or dripping into said doorway, and with baiiles to prevent movement of the moisture longitudinally of the. car'on portions 4I.

It is thus apparent that there is provided a very eifective flashing arrangement for overhead bunker refrigerator cars which will positively prevent any moisture dripping inthe doorway when the doors are open, or contacting theY door posts of the car.

The accompanying drawings illustrate the preferred form of the invention, though it is to be understood that the invention is not limited to the exact detailsl of construction shown and described, as it is obvious that various modications thereof, within the scope of the claims, will occur to persons skilled in the art.
